Mr. Mills, it has been very interesting to hear your perspectives on this after, as you say, many years of looking at this issue.
You mentioned that we must sort at the front end. I think it's key. Mr. McKay talked about this a little bit. Where do you see that front end when it comes to sorting occurring? We've heard from different witnesses. Some will see that front end as being at the household before it gets to the curb. Some will see that sorting at different points. Where would you define that front end from your perspective?
